NASA’s James Webb Space Telescope, reaches destination in solar orbit

NASA’s James Webb Space Telescope, designed to give the Earth an unprecedented view of the first stages of the Earth, landed at its gravitational pull in orbit around the sun on Monday, about one million miles from Earth.

With the final repair game made by rocket-propelled grenade launchers, Webb reached its destination at the landmark between Earth and the sun known as Lagrange Point Two, or L2, and arrived one month after its launch, the space station said.

the Space Telescope Science Institute in Baltimore, and the lower team used radio signals to ensure that Webb was successfully “inserted” into the orbital loop around L2.

From its prominent position in space, Webb will follow a special “halo” system in constant harmony with the Earth, as the planet and the telescope rotate in the sun in harmony, resulting in uninterrupted radio communications.

By comparison, Webb’s 30-year-old predecessor, the Hubble Space Telescope, orbits the Earth from 547 kilometers, entering and leaving the planet’s shadow every 90 minutes.

The solar system’s orbit at L2 will hold the telescope firmly in place and therefore take a little extra effort to keep Webb from moving, Eric Smith, a NASA program scientist for Webb, told Reuters in an interview last week.

The mechanical engineering center has begun to refine the main telescope – a series of 18 hexagonal segments of 21-foot gold-plated beryllium metal, 4 inches (6.5 m) horizontally – much larger than the Hubble’s large mirror.

Its size and its highly functional design in the infrared spectrum will allow Webb to look at clouds of gas and dust and look at objects farther away, thus later, than Hubble or any other telescope.

These trends are expected to revolutionize astronomy, giving the first impression of the newborn galaxies dating back 100 million years after the Big Bang, a theoretical study that put the known cosmic expansion about 13.8 billion years ago.

Webb’s observations make it ideal to search for signs of life around the newly discovered exoplanet – celestial bodies orbiting distant stars – as well as to see the nearest land, such as Mars and the colder Saturn Titan.

THE FOLLOWING STEPS

It will take another few months of work to prepare Webb for it to start appearing in space.

Eighteen parts of its main mirror, which were folded together to fit inside a rocket cargo that carried a telescope in space, were unveiled to all parts of the building within two weeks after Webb’s launch in Dec. 25.

Those segments have just been separated from the connectors that hold them in place at the start and gradually progress to a fraction of an inch from their original configuration, allowing them to be adjusted into a single, uninterrupted, light-collecting space.

The 18 stages now require compliance to achieve the proper focus of the mirror, which is a process that will take three months to complete.

As the direction goes, the lower classes will begin using the spectrograph, camera, and other observatory equipment. This will be followed by two months of measuring the instruments themselves, Smith said.

If all goes well, Webb should be ready to start looking at the beginning of the summer, with the first photos used to show the tools that work well.

But Smith said Webb’s most important work, including programs to train his mirror on things far away from Earth, would take a long time to do.

The telescope is a NASA-led international collaboration in space with European and Canadian space agencies. Northrop Grumman Corp was the main contractor.
